A view is counted when a device makes a request to the Variant API for product data and assets. Some devices will cache this response, meaning repeat visits will not count towards views, but this depends on the specific device's configuration.

Storage is calculated as the total of all assets you have uploaded for the product, including any assets that were generated from converting files into the correct format. 

The number of variations possible from those assets does not count towards your product storage. For example if you upload a 5MB file that can generate 10 different variants, your storage only counts as 5MB.
